Lead Frontend Engineer

As a Lead Frontend Engineer with a focus on frontend, you shape the technical direction of our eCommerce platform exactly where architecture, developer experience, and conversion intersect. You work across teams and domains, set standards for the entire frontend landscape, and ensure that our independently deployable systems (Self-Contained Systems / Micro-Frontends) deliver a consistent, fast, and accessible customer experience - without restricting the autonomy of the teams.

You lead through technical excellence instead of through a reporting line: At our Principal Engineer level (Individual Contributor track), you take on technical leadership and act as a coach, role model, and sparring partner for engineers, team leads, and our domain architecture.

Lead Frontend Engineer

What awaits you

• You are responsible for the frontend architecture across multiple teams and domains - from the storefront through checkout and search to account and loyalty flows.
• You establish and develop our standards for React, TypeScript, and Server-Side Rendering (SSR) as well as for micro-frontend integration, design systems, and shared component foundations.
• You drive web performance and Core Web Vitals as direct conversion levers: rendering strategies (SSR / Streaming / Edge), bundle budgets, caching, and frontend observability (Real User Monitoring).
• You remove blockers that slow down the entire engineering organization - from productive local development through tooling and build pipelines to architectural misalignments.
• You ensure that security, accessibility (a11y), and privacy by default are lived throughout the entire frontend landscape.
• You represent our technical direction externally - in the tech community and towards leadership and budget holders.

You strongly identify with a culture in which

• Technical full-stack thinking, pair programming, whiteboard sessions, code reviews, automated testing, and CI/CD with multiple productive releases per day are normal. Teams take on real end-to-end responsibility in the sense of "You build it, you run it".
• Servant leadership, benevolent feedback, and the targeted development of people and the organization go hand in hand.
• Product engineering works with engineering, wants to understand problems in depth, lives true agility, relies on MVPs, short iterations, and fast learning, and consistently makes decisions from a user and business perspective.

What you bring with you

• You bring deep expertise in modern frontend: React and TypeScript at production level, sound experience with SSR (Server-Side Rendering, e.g., with , Remix or a comparable setup), micro-frontends / Self-Contained Systems, as well as a sharp sense for web performance, Core Web Vitals, and accessibility.
• You bring experience in domains such as account, product data, checkout, or user-generated content, or you are generally well-versed in the e-commerce environment.
• You not only know the described culture, but live it, coach it, and anchor it in the organization, contributing to a strong team culture with appreciative communication, warmth, and a good dose of humor.
• You are a great coach and role model for engineers, team leads, and the organization - without formal authority, but with technical authority and personal connection.
• You tackle complex topics with perseverance and resilience and are perceived as a motivating lighthouse even in demanding situations.
• You define the AI tooling strategy for the frontend, create the architectural prerequisites, and establish best software practices, for example through automated code reviews. Tools like Claude Code are used effectively in the daily work of the teams - and you ensure that AI-generated code respects design system boundaries.
• You use frontend-specific patterns confidently - Component-Driven Development, design systems, state management, and edge/server rendering - and establish them structurally across teams.
• You decide based on data: Core Web Vitals, conversion, flaky tests, and technical debt are signals for you, not goals. You understand OKRs as a tool to target your influence across teams.
• You bring at least 10 years of experience in modern software development with a heavy focus on the frontend, of which at least 2 years in a technical leadership or architecture role.
• You speak German and/or English.
